IMPROVEMENT I' GATES.

The Schedule referred to in these Letters Patent and making part of the same.

provement in Gate-operating Apparatus; andlI do hereby declare that the following is a full, clear, and exact description thereof, whichwill enable others yskilled in the Iart to make and use the saine, reference being had to the accompanying drawing forming part of this specilcation.I

This invention relates to improvements in gate-operating apparatus; and

It consists in the application to the hinged end of the gate of a projecting arm and friction-roller, and in the Combination therewith of a pair 'ot' plates hinged together and connected by chains with an operatinglever and cords, all soarranged that onapproaching the gate from either side and pulling the cord the gate maybe raised, unlocked, v and swung open by one of theplates acting lunder the'l roller and 'taking the weight offthe hinges upon its oblique side; then, on pulling. thesame 'rope again, the other plate, similarly acting on the roller, will .cause the gat'e to shut again, all as hereinafter described. l

Figure 1 isa horizontal section of a gate provided with my improved apparatus; v

Figure 2 is an end elevation; and

Figure 3 isa front elevation.

Similar letters of reference indicate corresponding parts. I The gate A is mounted on loose hinges B, which allow it to be raised, and it is provided with a projecting arm, '0, at the rear or hinged end, in which arm is mounted a roller, D.

' The armis so shaped that the roller is supported at some distancefroln one'sidc of the post E, to which the gate is hinged.

on 'a fixed stud, H, projecting from the said post.

They are capable of swinging vertically above and 'below the horizontal' plane of the pivot-stud H, and

are connected to the chain I, whiclrworks overthe guide-pulley K, and is attached to the operatinglevers L by the branches M -N, Vone connecting aboveV Aand the other below the pivot-joint O, so'that no Vforth over them` when thegate opens' and closes, and

F and G represent a pair of plates, hinged together the studpiu II is placed nearly or quite as high as the axis of the'whecl D- is when the gate :is closed, so that when the gatev opens or closes it must ,rise for the wheel to pass over the pin.

Cords l), connected to the upper end of lever L, which is mounted on a post, Q, at one side of the gate, -are stretched over suitable supports, so that one approaching either side of the gate may Ahave the means of moving the lever to operate the gate.

The said' lever being moved 'either-way, and the plates F G thereby raised'so that the free ends will be higher than the stud-pin H, the gate will be raised by the oneover which the roller D is, and the incli-y nation of the 'surface of the plate E, ouwhich the roller rests, if closed, will cause the gate `to swing open, the said roller running down the plate across the stud-piu, when the gate isl about half open, onto the plate G, which, being Aallowed to fall bylet-tiug go the cord Il at the proper time, the gate will swing wide open and be held so. Then, by another pull on the cord, the gate will be raised by the plate Hand caused to swing shut in the same manner.

The raising ot' the gate prior to the swinging open disengagcsV the latch R from its catch to admit of' the opening. p

As a gate arranged on hingcsin this manner to rise freely is liable 'to be raised by hogs and other animals, I have provided the sliding bar S ou the gate,.and the pin T on the post, to prevent it, and for disengagiug it I have attached it to thechain I by a short piece, (d, workingthrough a guide, so that when the gate is to be opened the said bar S will be drawn back.

Having thus described Iny invention,

I claim as new, and desire to secure b y Letters Pat'- ent- ' 1. The combination, with the gate A, or' the roller D, hinged plates F G, and operatingchain I, substantially as specified.
